A Comprehensive Review of Cybersecurity Attack Vectors and Mitigation Strategies

The escalating frequency and sophistication of cyber threats pose a critical challenge to individuals, organizations, and societies that have grown deeply dependent on digital technologies for communication, commerce, and daily operations. Despite this growing risk, a significant portion of everyday users remains unaware of the nature and scale of these threats, while existing literature continues to address attack vectors and their countermeasures in a fragmented and disjointed manner — motivating the need for a consolidated, rigorous review. Data has emerged as the most valuable asset of the digital age, underpinning organizational operations, personal identity, and economic activity, making it an increasingly attractive target for malicious actors who exploit both technical vulnerabilities and user complacency with growing precision. This review examines how major cyber-attacks manifest, traces their documented real-world impact across history, and evaluates the effectiveness of current technical and human-based mitigation strategies. In doing so, it provides a comprehensive, up-to-date synthesis that maps specific attack vectors to their historical implications while assessing the emerging role of AI-driven defense mechanisms. The findings aim to bridge the gap between theoretical understanding and practical cyber defense, offering the academic and practitioner community a unified analytical perspective that strengthens collective resilience against an increasingly hostile digital environment.
